An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2015-2311 in the wild and no public exploit code.\n\nAffected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2015-2311/ (Markdown: https://insights.sbomify.com/CVE-2015-2311/index.md)","id":"CVE-2015-2311","markdown":"https://insights.sbomify.com/CVE-2015-2311/index.md","name":"CVE-2015-2311","record":{"aliases":["DEBIAN-CVE-2015-2311","GHSA-w3xw-rq95-8jcw","UBUNTU-CVE-2015-2311"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cap'n Proto library","requires_auth":"none","summary":"Remote attackers can trigger an integer underflow in Cap'n Proto to execute code, cause denial of service, or read memory.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"debian","cpe":[{"product":"capnproto","vendor":"capnproto"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"Integer underflow in Sandstorm Cap'n Proto before 0.4.1.1 and 0.5.x before 0.5.1.1 might allow remote peers to cause a denial of service or possibly obtain sensitive information from memory or execute arbitrary code via a crafted message.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow in n/a","id":"CVE-2015-2311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2015"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2015-2312"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2015-2310"},"products":["n/a"],"published":"2017-08-09","related":[{"cvss_score":9.1,"headline":"Integer overflow in n/a","id":"CVE-2015-2310","kev_date_added":null,"published":"2017-08-09"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2015-2312","kev_date_added":null,"published":"2017-08-09"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2015-2313","kev_date_added":null,"published":"2017-08-09"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2017-7892","kev_date_added":null,"published":"2017-04-17"},{"cvss_score":6.3,"headline":"Cap'n Proto has an integer overflow in KJ-HTTP","id":"CVE-2026-32239","kev_date_added":null,"published":"2026-03-12"},{"cvss_score":6.3,"headline":"Cap'n Proto: Integer overflow in KJ-HTTP chunk size","id":"CVE-2026-32240","kev_date_added":null,"published":"2026-03-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can trigger an integer underflow in Cap'n Proto to execute code, cause denial of service, or read memory.","url":"https://insights.sbomify.com/CVE-2015-2311/"}
